 2.1 Connection between indicator and load cell

Excitation voltage of this controller is DC5V, maximum exciting current is 350 mA, can be connected with 8 pcs 350 Ω load cell.

The figure below marks the meaning of each pin:

The load cell is connected with 6-wire (long-wire compensation mode). If the load cell uses 4-wire, "E+" and "F+", "E-" and "F-" must be shorted together on the load cell plug of the controller. If not connected, the controller will not work.
